 In trunk, a JS error in thrown in your mousedown on an element that is not
 an image and has no child elements.

 This is due to the wpEditImage mousedown handler:

 {{{
 if ( e.target && (e.target.nodeName == 'IMG' ||
 e.target.firstChild.nodeName == 'IMG') ) {
 }}}

 Steps to reproduce:

 1. Create a new post, paste the folling into the HTML view
 {{{
 <input type="text" value="foo" />
 }}}

 2. Switch to Visual, click on the input

 Observed Result:
 JS Error "Uncaught TypeError: Cannot read property 'nodeName' of null"

 Attached patch to fix
